WRENCH.

S1 ECIFICATION forming part of Letters Patent No. 774,916, datedNovember 15, 1904. Application filed July 23, 1904. Serial No. 217,829.(No model.)

To all whom it may concern:

Be it known that I, LOUIS HANEKE, a citizen of the United States, and aresident of Eureka Springs, in the county of Carroll and State ofArkansas, have invented a new'and useful Improvement in Wrenches, ofwhich the following is a specification.

My invention relates to an improvement in wrenches; and the object is toprovide a quick acting and powerful wrench consisting of few parts andwhich can be manufactured and put on the market at a comparativelyslight expense.

With the foregoing object in view this invention consists in certainnovel features of construction and combinations of parts, which will behereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a rear view of my improvedwrench, and Fig. 2 is a side elevation.

A represents the main bar of the Wrench, 3 is the fixed jaw at the outerend of this bar, and 6 indicates the adjustable sliding jaw mounted onthe bar A and capable of being set at various positions from jaw 3. The1igsual handle 18 is provided at one end of the J aw 6 is provided withratchet-teeth on its rear edge adapted to register withcorrespondingly-shaped teeth on the locking-bar 7, the latter beingpivoted in the rear end of jaw 3 in a recess 1, formed for that purpose,by means of a pin 5, which construction admits of the locking-bar beingswung away from jaw 6 to permit the latter to be slid and adjusted alongthe bar A to suit the size of the nut to be turned. As the locking-bar 7and jaw 6 have an extended toothed surface, it affords a rigid andsecure fastening for the jaw when the locking-bar is in the positionshown in the drawings.

Provision is made for locking bar 7 against the jaw through the mediumof a spring-catch 9. This catch is pivoted upon a pin 10 in the yoke 8,mounted on the bar A of the wrench, and the end 11 of this catch isnormally held in contact with the locking-bar 7 by means of aplate-spring 18, secured to the catch by the screw or rivet l4 andengaging at its free end a pin 15, which extends across from one side ofthe yoke 8 to the other. The catch 9 is provided with a thumb-piece 12,which extends rearward in the direction of the handle where it can beeasily pressed by the thumb of the operator when it is desired torelease and adjust the sliding jaw 6. A spiral spring 16 in the pocket17 presses outwardly upon locking-bar 7, so that the moment thethumb-piece 12 of the catch 9 is pressed inwardly the spiral spring 16acts upon the rear end of locking-bar '7 to force it outwardly and itsteeth away from the teeth on jaw 6. The moment these teeth clear eachother jaw 6 may be slid back and forth to the required 5 position on thebar A, whereupon lockingbar 7 is returned to the position indicated inFig. 2 and the catch to the position indicated in that figure,when theparts are all securely locked together. There is little or no 7 outwardpressure from jaw 6 upon locking bar 7, and hence the tension of spring13, bearing upon pin 15, is suflicient to hold the end 11 of catch 9 incontact with locking-bar 7.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of my invention, and hence I do not wish to limitmyself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination with a main bar, fixed and movable jaws of a wrench, themovable 5 jaw having teeth thereon, of a spring-actuated locking-barhaving teeth adapted to register with the teeth of the movable jaw, ayoke mounted on the bar, a catch pivoted thereto, and a spring securedto the catch and adapted 9 to hold the latter normally against thelocking-bar.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

LOUIS HANEKE.
